WattStopper BZ-200 – Frequently Asked Questions

1) Can the WattStopper BZ-200 power pack be installed in a plenum ceiling space?
Yes. The BZ-200 is UL 2043 plenum rated, so it can go in an air-handling ceiling space without a separate enclosure or fire-rated barrier around it. That is the usual reason this pack gets specified over a non-rated supply on a commercial ceiling retrofit.
2) Will the BZ-200 work on 277V lighting circuits, or do I need a separate 120V version?
One part covers both. The BZ-200 takes a universal 120-277V input at 50/60Hz, so the same power pack goes on a 120V tenant circuit or a 277V commercial lighting branch. No separate voltage-specific model to stock.
3) How many occupancy sensors can I run off a BZ-200 power pack?
The BZ-200 puts out 24VDC at 225mA. Add up the milliamp draw of the low-voltage sensors you intend to connect and keep the total at or under 225mA. Sensor current draw varies by model, so size the count off the sensor's own rating rather than a rule of thumb.
4) How does the BZ-200 power pack mount to a junction box?
It attaches through a 1/2 inch knockout using the integral 1/2 inch threaded nipple, so the low-voltage wiring stays inside the pack and the line-voltage leads land in the box. Standard electrical enclosures take it directly, no adapter plate. The body measures 4.0 in wide, 3.8 in deep and 2.7 in high, so check you have that clearance above the ceiling or beside the box.
5) Is the BZ-200 rated for switching LED drivers and electronic ballasts?
It is NEMA 410 tested, which covers the inrush current electronic ballasts and LED drivers pull at switch-on. That is the test a spec writer looks for when a relay is being asked to hold up against driver inrush rather than plain incandescent load.
6) How do I tell if a BZ-200 has a low-voltage short on the sensor wiring?
There is an LED on the pack that indicates relay status and also flags low-voltage overcurrent. If the sensors go dead and that indicator shows an overcurrent condition, you are looking at a short or an overloaded low-voltage run rather than a failed pack. The unit carries built-in short circuit and thermal protection, so it shuts the low-voltage side down instead of damaging itself.
7) What is the exact part number to order for the WattStopper BZ-200 power pack?
Order it as WattStopper BZ-200. That is the manufacturer part number and the only configuration of this pack, 120-277V in, 24VDC 225mA out. Country of origin is China.
8) Is the BZ-200 light enough to hang off the junction box in a ceiling grid?
At 0.5 lb it is supported by its own 1/2 inch nipple connection into the enclosure knockout, which is how these packs are normally mounted above a ceiling. No separate strut or bracket needed for the weight.
